How to use the @redux-saga/core/effects.effectTypes.RACE function in @redux-saga/core

formatter
        .addEffectType("take")
        .resetStyle()
        .addValue(payload.channel == null ? payload.pattern : payload)
        .addDescResult(desc);
    } else if (type === effectTypes.PUT) {
      formatter
        .addEffectType("put")
        .resetStyle()
        .addDescResult(Object.assign({}, desc, { result: payload }));
    } else if (type === effectTypes.ALL) {
      formatter
        .addEffectType("all")
        .resetStyle()
        .addDescResult(desc, true);
    } else if (type === effectTypes.RACE) {
      formatter
        .addEffectType("race")
        .resetStyle()
        .addDescResult(desc, true);
    } else if (type === effectTypes.CALL) {
      formatter
        .addEffectType("call")
        .resetStyle()
        .addCall(payload.fn.name, payload.args)
        .addDescResult(desc);
    } else if (type === effectTypes.CPS) {
      formatter
        .addEffectType("cps")
        .resetStyle()
        .addCall(payload.fn.name, payload.args)
        .addDescResult(desc);

export const isRaceEffect = eff => is.effect(eff) && eff.type === effectTypes.RACE;
